Airtac MAC Stainless Steel Mini Air Cylinder MAC32X275SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X275SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 275mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.

About the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X275SU
With 275 mm of travel and a 32 mm bore, the MAC32X275SU double-acting cylinder pushes 402.2 N at 0.5 MPa - read that as roughly 41 kgf of push, or about 20 kg of vertical lift once you hold a 2:1 safety margin. Speed range is 30-800 mm/s and the supply window is 0.15-1.0 MPa (22-145 psi).
Its U flat-end back cover gives a clean fixed face for direct bolting to a machine plate, sparing you an adapter bracket. Construction is a rolled stainless round barrel with a hard-chrome plated carbon-steel rod, so damp workshops and washdown zones corrode it slowly if at all. Needle-screw air cushions at each end let you tune deceleration so the last millimetres arrive quietly even at higher speeds.

Specifications follow the official AirTAC MA-series datasheet. Barrel: stainless-steel tube (round-body, riveted rolling-packed construction); piston rod: carbon steel with 20µm hard-chrome plating; covers: aluminium alloy. Thread options: PT (blank) / G / NPT. Every MA-series cylinder ships with a built-in magnet for CMSG / DMSG / EMSG position sensors.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X275SU Is Used
Case packer pusher
Sweeping cartons sideways into a case on a secondary packaging line, the flat-end cover bolting straight to the machine deck.
Chip conveyor gate
Diverting swarf flow between two bins under a CNC machining centre, where coolant mist favours the stainless barrel.
Pallet stop anchor
Cycling a stop blade on a small pallet transfer car in a warehouse shuttle, with cushions catching each stop cycle.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X275SU the Right Cylinder?
A 25 mm bore (245.3 N push at 0.5 MPa) suits lighter jigs, while the 40 mm bore (628.3 N) handles roughly 370 N of genuine working load. Do not count on this cylinder to hold position: with no air applied the piston floats, so add a rod lock or pilot check valve for parked loads.
The flat-end U cover bolts flush to a plate, and LB foot, FA flange or SDB pivot brackets are there if the layout needs them. The magnet comes as standard equipment, so CMSG, DMSG and EMSG switches drop on without special ordering. Over a 275 mm stroke, keep the load guided in its own bearings so the 12 mm rod sees little side load.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) is standard for sensors
- ✓ Back cover (CA/U/CM) & mount (FA/LB/SDB)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MAC Stainless Steel Mini Air Cylinder MAC32X275SU FAQ
No - it is double acting without any lock, so the piston drifts when supply drops; fit a rod lock or pilot check valve. For sizing: 402.2 N push and 345.6 N pull at 0.5 MPa, 563.0 N push and 483.8 N pull at 0.7 MPa, 82 kgf theoretical maximum at 1.0 MPa.
Both needle screws ship closed. Open them fully for the initial strokes, then close gradually until the 275 mm stroke lands without a knock - that tune changes with pressure, speed and load.
